Sen. Arlen Specter (R-Pennsylvania) vowed to haul the companies before his committee in response to the USA Today report that says the NSA has been secretly using data provided by AT&T, Verizon and BellSouth to build a massive database of foreign and domestic phone calls. The program was launched shortly after the Sept. 11, 2001, terrorist attacks with the aim of analyzing calling patterns to detect terrorist activity, the paper reported. The effort does not involve recording or eavesdropping on phone conversations, it said.
